摘要
本文利用LHCb实验Run 2采集的质子-质子对撞数据，对Bs0→J/ψπ+π-衰变进行了时间依赖的味道标记振幅分析和螺旋度振幅分析。分析测量了CP破坏相角ϕs和寻找了四夸克态粒子Zc±。
Abstract
A time-dependent flavour tagging amplitude analysis and a helicity amplitude analysis are performed to Bs0→J/ψπ+π- decays, using the Run 2 pp collision data collected with the LHCb detector. The CP-violating phase ϕs is measured and the tetraquark state Zc± is searched.
